We present the Greek population data of the study. METHODS: An observational multicenter, cross-sectional study evaluating glycaemic control and a range of other clinical and biological measures as well as quality of life(Qo L) and treatment satisfaction in 375 patients with T2 DM enrolled by 25 primary care sites from Greece. RESULTS: The mean age of the patients was 63.5 years and the male/female ratio 48.9%/51.1%. 79.7% of the patients exerted none or light physical activity, 82.4% were overweight or obese and 32.9% did not meet Hb A1 c target of less than 7.0%(53 mmol/mol). Patients reported high satisfaction to continue with treatment, high satisfaction with administered treatment and increased willingness to recommend treatment to others(mean Diabetes Treatment Satisfaction Questionnaire score 29.1 ± 5.6). However, 80% of the patients reported that their Qo L would be better without diabetes. Finally, the most challenging parameter reported was the lack of freedom to eat and drink. CONCLUSION: This analysis of the Greek Panorama study results showed that a considerable percentage of T2 DM patients in Greece do not achieve glycaemic target levels, despite the favourably reported patient satisfaction from administered therapy. Additionally, the majority of primary care T2 DM patients in Greece depict the negative effect of the disease in their Qo L.展开更多

Methods 96 consecutive patients admittedwith CHF between September 2002 and January 2003 were stud- ied , upon entry the study, BNP levels were measured, Patients administered the disease - specificquality of life questionnaire Minnesota living with heart failure questionnaire (LiHFe) within 1 day. BNP levels and administering LiHFe were repeated three months later. Results BNP levels were increased proportional to the severity of cardiac function. Physical domain and total score of LiHFe were significantly correlated to the severity of CHF ( p < 0. 05 ). BNP levels were de- creased in improving group(p =0. 032) . In deteriora- ting group BNP levels increased (P = 0. 043 ) . Kaplan - meier analysis according to BNP level cutoff point 150 ng/1, the life curve of higher BNP level group was significantly lower than the lower group ( p = 0. 001 ) . In univariate logistic regression, NYHA class, BNP, LVEF, LVEDD, heart size, total score of LiHFe, phys- ical domain of LiHFe and the emotional domain of LiH- Fe were all significant prognostic factors of CHF ( p < 0. 05 for all). While in multiple regression, only BNP level( p = 0. 036) and the emotional domain of LiHFe ( p = 0. 025 ) were independent prognostic factors. Conclusions Change of BNP reflects the treatment efficacy of CHF. BNP and QOL are the two major short - time prognostic factors of the chronic heart failure patients.展开更多

The maximum likelihood estimation （MLE） of the parameters is obtained through the numerical method for solving the likelihood equations. Approxi- mate confidence interval （CI）, based on normal approximation to the asymptotic distribution of MLE and percentile bootstrap Cl is derived.

Objective: To assess the health related quality of life in adult with type 2 diabetes mellitus. Materials and methods: A cross-sectional study was conducted to assess diabetic patient’s HRQoL on 119 purposively selected type-2 DM patients (aged ≥ 18 years and duration of diabetes ≥ 1 year). Data were collected by face-to-face interview and by medical record review through a Bangle version of SF-36 semi-structured questionnaire and a checklist. Place and period of study: The study was conducted at outpatient department in Gopalganj 50 bedded diabetic hospital from 1<sup>st</sup> January, 2018 to 31<sup>st</sup> December 2018. Results: The mean age of the respondents was 52.34 (SD ± 10.19) years. Age group shows a significant difference associated with all domains of quality of life except role emotion (>0.05), gender shows the significant in social and pain domain (0.05) respectively co-morbidity shows the significant difference with all domains expect pain (>0.05). Physical functioning, emotional, pain and general health of the quality of life show the significant difference associated with use of insulin (Conclusion: The overall QoL of type-2 DM patients was poor and had lower score of health related quality of life.展开更多
